title: Severe complication of a Zenker's diverticulum with endoscopic diverticulotomy rescue.
abstract: Persistent pharyngoesophageal obstruction precipitated by lodgement of a foreign body in a Zenker's diverticulum, with abscess formation, was successfully treated by endoscopic diverticulotomy. The symptoms and pathogenesis of Zenker's diverticula are fully described, emphasizing the importance of the cricopharyngeus and party wall in its development and relentless progress. Transcutaneous resection of diverticula is reviewed. Detailed description of the technique of endoscopic diverticulotomy is outlined. The rationale and indications for the endoscopic approach are delineated.
